South Korean scientists have taken tips from the prehistoric Velociraptor dinosaur to build one of the world's simplest and fastest robots, capable of reaching a speed of 46 kilometers per hour (28.5 mph).

Just like the carnivore that roamed the earth 75 million years
ago, the ‘Raptor’ robot has two legs and a mechanism that works
like a tail. The machine was built by the Korea Advanced
Institute of Science and Technology (KAIST).

According to the scientists behind the project, the spinning rod
- which executes the function of the tail - provides stability to
the robot, helping it navigate around obstacles.
